The Shadow or the Leaf

What came first, the shadow or the leaf
it falls upon,
the sunlight or the pain?
Painted yellow, what calls, and what echoes, and what cries
through the valley;
And what strains the surface of things
when joy surges and the depths reach up,
and the wet sand dries and blows unseen to the dune ...
And what settles over my head,
misty and mysterious, indivisibly fine ...
